Excel 2003 asks me for a protected worksheet password every time I start Excel
 

I'm running Excel Version 11.5612.5703 One of the workbooks that I use
is password protected and it recently started asking me for the
password for that workbook every time I start Excel. I posted the same
problem a while ago and somebody suggested that the file could be in
my XLSTART folder - which it was so I removed it and the problem went
away. This time I have checked XLSTART, in fact I have searched the
whole machine including the registry but can't find anything to
explain this behaviour. Incidentally, if I enter the password it opens
the workbook straight into editable mode without prompting again to
make it writeable.

Has anybody had the same problem?

Thanks,

Liam
